I am high porosity and high density - sleeping usually doesn't bother my hair. I don't get extended hair if I play with it to much or if I pull it back into a French braid or something similar. Once the curls get pulled out, they don't come back unless I rewet it.
High Density, High Porosity, Medium Texture, 3B with some kink
